Some people prepare lighter keys... almost toylike...

I think its the less advanced players like you and me that take to a heavier keyaction much more, as that seems to give us more controll over our performance..

i stay away from the ultra light keybeds of the psr-s keyboards

however many others here just dont seem to mind it, and even prefer it for getting less fatigue during long playing sessions.

In the end i guess its more about what you are used to, as long as you only play the psr-s keybed, you will not notice how incredibly light the touch is.
